There are not many kilometers left for the James Webb Telescope to reach its target orbit at the L2 Lagrange point. It is a milestone for science, especially since everything has worked without complications so far.
Only a few kilometers from Langrange Point L2
Within a few hours, the James Webb Space Telescope (JWST) reached its orbit around the Sun. This orbit is located at the level of the Lagrangian point L2. Only a few thousand kilometers separate the space telescope from the point of aim. Lagrange point is located 1.5 million km from Earth. So the scientists were happy that the telescope had opened without any problems. They were sure at that time of repeated postponement Ariane 5 missile launch Not. At a distance of 1.5 million km, it will not be possible to carry out repairs on the telescope for the next twenty years. 20 years is the time that telescope fuel lasts.
Look at the past of the universe
Appointments for the use of the telescope by scientists around the world during the “lifetime” are already fully booked. No wonder, after all, the telescope is expected to be able to glimpse the past of space. Light from faint stars that existed 13 billion years ago In progress it will be able to capture it with a telescope mirror. In addition, space authorities hope to get a better look at exoplanets from other solar systems. However, it will be another six months before this happens. This is the amount of time NASA needs to properly calibrate all of the equipment and align the telescope.
